Disclosure: we're Ryz Labs, the first pick on this page, so weigh our view with that in mind. We think we're the right call for engineering teams, and we name the cases where Athyna or another firm fits your needs more closely. Facts about other companies come from their own sites and filings, listed under Sources.
Athyna is a fully remote hiring platform that uses AI matching to fill roles across marketing, design, operations, tech and finance. It says it finds talent in five days or less, and you pay only for the talent you hire. A newer arm, Athyna Intelligence, supplies Latin American PhDs and domain experts for evals, red-teaming and RL environments. Buyers look for alternatives when the job is narrower than a platform built for every function: senior software engineers who share their hours, or a team that builds and ships an AI system for the business rather than helping train a model. Others want a different kind of marketplace altogether. Here's the field.
If the roles you're filling are engineering roles, start with Ryz. Fortune 500 engineering teams trust us, only the top 1% of the tens of thousands of engineers we've interviewed make it, and our people are mostly mid-level to senior. Every one of them is in Latin America and works US business hours, including New York hours, so standups and same-day code review are the default rather than a matching criterion. They work on your team, in your repos, from week one.
The bigger difference is AI. Athyna Intelligence helps AI labs train and evaluate models. Our AI pod teams build AI systems for your business: a dedicated pod of senior engineers, often about seven with a tech lead and an ML engineer, working in your AWS or Azure account and your GitHub with Anthropic and OpenAI models. One pod built an AI driver-support agent that covers about 218,000 driver calls a year in three languages; another runs an AI voice platform with 1M+ outbound calls. See our case studies and the head-to-head, Ryz Labs vs Athyna.
Athyna prices per hire, and its sample profiles show hourly rates. Ours are monthly and public: $7,000 to $10,000 for mid-level engineers, $10,000 to $15,000 for seniors, and leads quoted per team. A pod is team size × duration × monthly rate, so six senior engineers for four months is 6 × $10,000 to $15,000 × 4, or $240,000 to $360,000. You get a plan, a price and the names of the people first.
Where we're not the right fit: you want a self-serve marketplace, short hourly gigs or a trial before you talk to anyone; you need people in Europe, Africa or Asia time zones; or you need PhD evaluators to train a model. Athyna, Index.dev or Upwork fit those better.
Revelo is a LatAm-only talent platform. It says it has 400K+ vetted developers across 18 Latin American countries, sends a curated shortlist in 48 to 72 hours, and that its engineers work within two hours of US Eastern. It offers a two-week risk-free trial and month-to-month billing, and day-to-day technical management of each hire stays with you. Pick it if you like Athyna's platform model but want every engineer in Latin America. See our Revelo alternatives.
Index.dev is the closest match to Athyna's two sides. Its global network of 30,000+ senior engineers, PhD researchers and evals specialists covers both product engineering and AI training work. It says it matches candidates in 24 to 48 hours, scales from one engineer to managed teams of 50, and backs engagements with a 30-day performance guarantee. It has offices in San Francisco, London and Chisinau and operates in 160+ countries. See our Index.dev alternatives.
Upwork is the open-marketplace option. It's a public company (NASDAQ: UPWK) that says it has 18M+ freelancers across 180 countries, and it publishes its client fees. Business Plus adds an Expert-Vetted filter and an AI shortlist in under six hours. You do the screening and day-to-day management, and time-zone overlap depends on each person you pick. It suits scoped tasks across many functions, much like Athyna's range, with more of the work on your side. See Ryz Labs vs Upwork.
If you need senior engineers on US hours, or an AI system built and running in production, talk to us. Our guides to companies to hire AI engineers and AI pod providers compare the wider field, and our page on how to hire LatAm developers covers stacks and countries.
Ryz Labs, if you want top 1% senior engineers on your team on US business hours, including New York hours. You see a plan, a price and the names of your engineers before work starts.
Index.dev, which lists PhD researchers and evals specialists alongside engineers. If you need an AI system built for your business rather than a model trained, a Ryz AI pod team is the better fit.
Athyna says Brazil, Argentina, Mexico and Chile operate within one to three hours of US Eastern. Its wider network reaches as far as Lagos, so ask where each candidate sits. Our engineers are all in Latin America on US business hours.
Upwork publishes client fees, Revelo quotes by calculator, and Index.dev charges nothing until you hire. We publish monthly ranges: $7,000 to $15,000 per engineer, mostly mid-level to senior.
We checked these platforms in October 2026. Fees, guarantees and services change, so confirm them with each one before you sign.
